Ports
Voice gateways arch the gap amid the VoIP apple and the acceptable telephony world
(for example, a clandestine annex barter [PBX], the accessible switched blast network
{PSTN], or an analog phone). Cisco articulation gateways affix to acceptable telephony devices
via articulation ports. This affiliate introduces basal agreement of analog and agenda articulation ports
and demonstrates how to fine-tune articulation ports with port-specific configurations. Upon
completing this chapter, you will be able to configure articulation interfaces on Cisco voiceenabled
equipment for affiliation to traditional, nonpacketized telephony equipment.
